# b4 vs Drop N Launch

The clearest difference is ratings volume: b4 at 152 against Drop N Launch's 21. Drop N Launch's advantage is device support (3 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. b4 sells 4 in-app purchases, starting at $3.99 per month and Drop N Launch sells 8 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

b4 holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: b4 has 152 ratings behind it against 21, so its average is the more settled of the two.
